BENJAMIN H. BURLING, OF FORT ANN, NEWV YORK, ASSIGNOR TO I IIMSELF AND JOHN CUNNINGHAM, OF SAME PLACE.

STEAM PROPELLING=RUDDER.

SPECIFICATION forming part of Letters Patent No. 284,812, dated September 11, 1883.

Application filed March 9, 1883. (No model.)

1'0 all whom it may concern:

Be it known that I, BENJAMIN H. BURLING, of Fort Ann, in the county of Washington and State of New York, have invented a new and Improved Steam Propelling-Rudder, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurel is a sectional side elevation of my improvement. Fig. 2 is a sectional front elevation of the same, taken through the line 0: m, Fig. 1. Fig. 3 is a sectional plan view of the s[ame, taken through the broken line yyyyy,

ig. 1. I

The object of this invention is to facilitate the steering and propelling of vessels.

The invention relates to a steam propellingrudder constructed with a hollowrudder, a steam-engine and a crank-shaft placed within the rudder, and a propeller placed at the rear edge of the said rudder. The rudder is connected with the keel of the vessel by a tubular pivot and a hand-screw passing through the said pivot and screwing into the said keel, whereby the rudder will be firmly held in place, and can be readily shipped and unshipped. The interior of the hollow rudder is provided with a ladder to allow an attendant to readily pass down into the said rudder, as set forth.

A represents the hull .of a vessel, and B is the keel. The rear end of the keel B has a socket, 0, formed in it to receive the pivot D, attached to the inner corner of the lower end of the rudder E, which corner is recessed to receive the end of the keel B. The pivot D is perforated longitudinally to receive the handscrew F, which passes through the said pivot D and screws into the keel B, so as to fasten the said rudder in place and prevent it from being accidentally unshipped.

The upper part of the rudder E works in bearings attached to the stern of the vessel A, and the said rudder-is operated by a tiller or wheel in the ordinary manner. The rudderoperating mechanism is not shown in the drawings, as there is nothing new in its con-5 struction.

The rudder E is made hollow and watertight, and is provided with a man-hole, G, through which access can be had to the interior of the said rudder.

H is a steam-pipe leading from a boiler or connecting-rod, N, theother end of which is pivoted to the crank or crank-wheel O of the shaft P. To the shaft 1? is also attached an eccentric, Q, with which is connected the valverod R, that works the valve of the engine. The shaft 1? revolves in'bearings S, attached to the rudder E, passes out through the rear edge of the said rudder, and has a propeller, T, attached to its rear end. The interior of the rudder E is provided with a ladder, U, to allow a man to enter the said rudder to take care of the engine, to remove the hand-screw when therudder is to be unshipped, and to insert the said screw when the rudder has been shipped.

- One, two, or more of the rudders E and their attachments can be used, as may be desired,

or as the size of the vessel may require.

With this construction the vessel will be driven by the action of the ,wheelsT when the rudders are parallel withthe length of the vessel, and will be turned by the action of the said wheels when the said rudders are turned to either side. closing the man-hole G, the rudder E can be floated to the stern of the vessel, then readily raised into a vertical position, and shipped.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a steam propelling-rudder, the rudder E, made hollow and water-tight, substantially as herein shown and described, and carrying a steam-engine, as set forth.

With this construction, also, by

held securely in place, and can be readily shipped and unshipped, as set forth.

4. In a steam propelling-rudder, the combi- I 5 nation, with the hollow water-tight rudder E, of the interior ladder, U, substantially as herein shown and described, whereby convenient access is had to the interior of the said rudder,

as set forth.
